So I am only change the device ID in 6850 bios,and began to flash.win flash don`t flash the my card it because he found that the subsystemid mismatch,so I flash card using some commandline params,and flashing done. After i reboot sysytem the card with new bios don`t starts,and i only can bot by use my PCI video,but winflash dont found not working amd`s 6790(and card dont present in device manager)! So I do some extra work to prepare boot DOS with atiflash and old bios!(with some difficults) I succesfull flash not working 6790 with he`s stock bios also with some commandline params in atiflash(at because at now he`s also find subsystemid and bios p/n mismatch) I can say that 6790 can`t be simply flashed to 6850 (maybe amd don`t lies about cutting blocks in 6790).And image,that be posted on china website-fake,and its probably 6850 card on the image,with changed DEVICEID from 6739 to 673E (6850>6790) http://detail.zol.com.cn/picture_ind...x6238766.shtml I am posting image that I take,when I flash my not working 6790(with 6850 bios) back to stock.
